Specification of Letters Patent.

' Application filedMa rch 17, 1913. Serial No; 754,727.

To all whom it may concern l 3e it known that I, JACOB H. MoRRow, citizen of the United States, residing at Eureka, in the county of VVoodford and A State of Illinois, have invented certain'new and useful Improvements in Elevators, of which the following is a specification.

My invention has reference more particularly to elevators wherein there is provided an adjustable receiving end section for maintaining the conveying device of the elevator at a tension to operate properly.

The object of my invention is toprovide the elevator with an adjustable boot section so formed with reference to the lower end of the elevator as to provide an uninterrupted continuous elevator passage way in its different positions of adjustment.

A further object is the maintaining of the elevator directing mechanism in the adjustable boot for the purpose of, regulating the tension of the conveying means by adjustment of the boot and also so as toprovidean unchanged relation between the conveying means and the bottom of the boot'in any position of adjustment.

A further object is the provision of means for delivering material into the boot which adjusts itself automatically to accord with the different positions of the boot.

A further object is the supporting of the boot by means of the conveying mechanism so as to automatically regulate the tension of the'conveying mechanism by means of the weight of the boot and the material contained therein.

The invention also embraces other features which will appear from the following specification and which are particularly pointed out in the claims.

Referring to the drawings Figure l is a side elevation of a portion of the elevator showing parts broken away to accommodate a view of interior arrangement of parts; Fig. 2 is a section on line c-a of Fig. 1; Fig. 3 is a partial section on line caa of Fig. 1, showing a slightly'different position of parts from that disclosed in Fig. 2, and in addition showing a means of fixing relatively movable parts; Fig. 4; is a sectional view on the line bb of 3 with the addition thereto of a diagrammatic illustration of a cross conveyer or drag. Mechanical devices for handling grain upon'the farm, and. particularly ear corn,

have come rapidlyinto use within the'last few years, in place of manual labor previously exercised in the use of scoops and the like. The portable dump and elevator has been the principal agency in this regard, wherein a wagon raising means called dump has been associated with an elevator and-built so light that the complete struc; ture was transportable from place to place. In'its use, such dumps and, elevators have been moved lengthwise of corn cribsor warehouses, and thus have proven adaptable for convenient filling and grain handling.

With the increase of wealth of the farmer, and in view of the demonstrated efficiency and utility of machine handling of grain, large permanent warehouses have been built to take the place of the old time corn cribs, which latter were of a more temporary character and of a cheap construction.

An elevator permanently built into a warehouse making it a part of such warehouse must be positioned substantially vertical as distinguished from the inclined position of an elevator in portable structures, therefore. the conveyer chain must bear the whole load and is under heavy strain and liable to stretch. It is one of the purposes of my invention to take care of this change in length of chain.

In handling ear corn with the vertical elevator, great difficulty has been experienced from clogging in the boot, caused by buckling of the conveyer chains. This has been due largely to a difliculty of maintaining a of the boot which permits husks, refuse, and even ears of corn to drop downwardly and j become wedged within the boot so as to obstruct operation of the conveying means within the boot. p

Referring to the drawings 2 refers generally to a casing whichmay be of general I rectangular shape provided with substan-j tially close side walls and with partially or wholly closed front and rear'walls.

3 refers generally to castings, being 10 cated respectively one upon each side of the elevator, a portionof such'sides being connected with framework of any suitable character to accommodate th'e support of" Said Castings nd to extend the elevator to any desired height. V

Referring to castings 3, e are channels formed in the inner face of the castings and are adapted to receive similar channel wayportions in castings hereinafter to be de scribed to facilitate relative adjustment of said castings in controlled lines, and also serving as a guideway or channel, through which'the conveyer chains-may travel. The

castings 3 are adapted to be connected by means of a rod 6 provided at each end with apair of adjustment nuts 7 to facilitate the proper spacing apart of said castings and to accommodate adjustment thereof to render their placement relative to the conveyeri mechanismin the proper relation to prevent bindmg, or too much lost space.

8 are. castings formed to sit within the.

offset 5 of. castings 3, said castings being provided with channels 9 previously ll'lCll cated, adapted to match with channels i] 'ofcastingsS. v r

l0 arestuds extending laterally from castings 8 adapted to. projectthrough elongated openings 11 in castings 3. This stud is provided with a central bore, within which is adapted to be carried the shaft 12, which shaft is adapted to extend across and which sprocketchains as 1st are adapted to be carried the latter carrying buckets 15, asshown in Fig.4. A front, bottom and rear housing wall 16 is provided, as shown. in Figs. 2 and l, adapted to form a closure j between the castings 3 and said wall may be extended and inclined as at.17 to meet a pivoted apron as 18' to form a chute leading to the boot of the elevator. I i

. 19 refers generally and in a diagrammatic manner to a drag or'cross conveyer that is adapted to be built underneath the floor of the driveway, and purposed to receive, through an openable way, the discharge of fm'ent of my invention and in a general way,

grain from the wagon and to deliver the same to, the elevator.

20 is a partition adapted to be fixed to guideway 22, the latter being formed by proper spacing of the frame parts of the elevator body. The partition 20 is adapted to have a bearing relation with partition 23, p which latter extends upwardly from its con nectionwith casting 3. i i

The spacebetween thepartition and the front and rear walls respectively of the boot and. the elevator form the passageway for the conveyer, and its buckets. The chains 7 14, when they leave the'channels 9"and castings 8, may be positioned relative to the side walls to be carried in channels formed in the elevatorframmg by properly spacing such framing substantially in the manner shown in the drawings. Two lugs as 21 are provided on casting 8, as shown in Fig. 4, merelyto provide interchangeability of said castings from side to side or to adapt them to use on either side of the elevator structure.

In the normal working of my device,-the boot portion of the elevator, comprising castingsS and their associated parts, including closure wall 16, is suspended from; sprocket chains 14:, thus fixing the position of the buckets with the closurewall 16, permanently so that there can be no variation of'their relationunder any normal condition. 7 The carrying of the elevator boot by thechains 14 serves to render them tight at all times. The facility forvertical adjustment between the boot and castings 3 form- I ing part ofv the elevatorbody, is permitted through the clearance provided in and by the elongated openings 11 in said castings 3, and I have shown by the channel formations i within castings3 and 8, guiding efliciency therebetween, and have likewise shown the facility for relative ustment betweenvpar for fixing the boot with relation tov the ele Y vator body or castings 8*thereofl Thismeans comprises threaded stems as 2 1-, which I may be fixed in connection with studs 10..

. 25 are perforatedlugs on castings 3 through whichthretided stems 24; are passed. 26. are

spacing nuts adaptedto' accomplish adjustment between the parts named and also serve to fix the parts in a definite position.

I have shown herein one :means of embodi- I the means disclosed has been demonstrated eflicient for the purpose, and is at present.

'my preferred form. However, I do not desire to be limited to the form disclos'edybut w wish the invention to apply to all forms that lie within the scope of the appended claims.1
